Hi! Like many of you, I deal with sensitive API responses and auth tokens daily. It always bothered me grabbing a JWT or a .env payload from the network tab and pasting it into the first Google result, knowing those free tools often log data on their backend. I couldn't find a suite I trusted, so I built DevNova. It’s a collection of 5 developer utilities that run entirely client-side via JavaScript. The decoding, formatting, and hashing logic executes directly on your local CPU using native browser APIs. I’m hosting the web versions completely free, and I also built a standalone desktop companion for anyone working in strict air-gapped or restricted network environments. I'd love to hear your feedback, or if there are any other specific utilities I should add to the dashboard!
